The DieHard brand is also used on hand tools, power tools, battery chargers, booster cables, power inverters, alkaline batteries, tires, work boots, and the batteries for Craftsman power tools. Battery chargers were initially made by Associated Equipment under the "608" model prefix, and then later Schumacher Electric under the "200" model prefix.
Silver–calcium alloy batteries are a type of lead–acid battery with grids made from lead–calcium–silver alloy, instead of the traditional lead–antimony alloy or newer lead–calcium alloy. They stand out for its resistance to corrosion and the destructive effects of high temperatures.

Alkaline batteries account for 80% of manufactured batteries in the US and over 10 billion individual units produced worldwide. In Japan, alkaline batteries account for 46% of all primary battery sales. In Switzerland, alkaline batteries account for 68%, in the UK 60% and in the EU 47% of all battery sales including secondary types.
Starting batteries are lighter than deep-cycle batteries of the same size, because the thinner and lighter cell plates do not extend all the way to the bottom of the battery case. This allows loose, disintegrated material to fall off the plates and collect at the bottom of the cell, prolonging the service life of the battery.
A 12V VRLA battery, typically used in small uninterruptible power supplies and emergency lamps. A valve regulated lead–acid (VRLA) battery, commonly known as a sealed lead–acid (SLA) battery, [1] is a type of lead–acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel; proportioning of the negative and ...
Mercury battery "РЦ-53М"(RTs-53M), Russian manufactured in 1989. A mercury battery (also called mercuric oxide battery, mercury cell, button cell, or Ruben-Mallory [1]) is a non-rechargeable electrochemical battery, a primary cell. Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte.
